Pacemaker function during irradiation: in vivo and in vitro effect.
With an ageing population in Australia, one would expect the probability of treating cancer patients who have a cardiac pacemaker to increase. In this paper the effect of ionizing radiation and electromagnetic interference on pacemaker function is discussed. A case of a cancer patient, with pacemaker, treated with radiotherapy without ill effect, is described. Concurrently, four pacemakers were tested in vitro with gamma radiation from a 60 Cobalt machine and no adverse effect was found. A list of precautions is recommended.
